Application filed December 13, 1927. Serial No. 239,674,

This invention relates to an apparatus which is more particularlydesigned for billboard and sign advertising.

Ci. he object of the invention is to provide a simple apparatus whichmaybe readily attached to a billboard or sign that carries advertisingmatter in whicii' the representation of the emission of smoke is'afeature to be depicted for producing the smoke.

This object is attained in the present instance by attaching a chambercontaining an electrically heated. resistance or hot-plate to the backthe billboard or sign and leading a pipe from the chamber to an openingin the billboard or sign at the locality where it is desired that smokeshall beemitted, a pipe from a reservoir or cup containing oil being ledinto the chamber over the hot plate or resistance so that oil may bedropped therefrom onto and be vaporized by the resistance or hot platethat is connected in a circuit which is closed by an electricallyoperated time switch that is also arranged to control the dischargeoutlet from the oil reservoir or cup, whereby the time switch may be setto simultaneously cause the resistance or hot plate to become heated andthe oil to drop thereon, at a definitetime for a predetermined period,and then 'coincidently shut off the current from the resistance or hotplate and stop the flow of oil. 7 p

In the accompanying drawings Fig. 1 1s a representation of a billboardprovided with an apparatus that embodies this invention. F 1g. 2 is aview of the apparatus on larger scale and with parts in section.

The chamber 1 may be attached to the back I of the billboard 2 by anysuitable means and the pipe 3 is led from the top ofthe chamber to thelocality where the smoke is to issue, which in the case illustrated isrepresented as thebowl of a smoking pipe l. llear the bottom of thechamber openings 5 are made to permit the entrance of the necessaryamount of air to promote vaporization of the constituents ot the oilthat are to make the smoke, and to ensure the necessary upward draughtof heated air which will tarry the smoke to the outlet up on thebillboard. Fastened to but insulated nected with this plate by bindingscrews 8 are wires 9 and 10 that lead from a time switch 11. This switchmay be any of the common well known types or electrically operatedswitches such as are used for street lighting,isigns, billboards, andstore windows for automatically turning on and off current atpredetermined times.

Extending on an incline into the chamber and having its lowe'rendopening abovethe cup 7 a tube 12. "The upper end of this tube isattached to the outlet end of an oil reserv'oi-ror'cup 13 ofcommonconstruction. The switch spindle 14 of the time switch FATE-NTorri'cs.

is extended throughthe switch casing and on theend of this spindle andfastened to it so as, to turn with the swltch in the usual manner is acam 15. The oil 'cup is located adjacent to the time switch in suchposition that this cam engages the head of the valve spindle 1601 theoil cup and forces the valve spindle down when the cam is turned to oneposition and allows thevalve rod to be raised by the spring 17 when thecam is turned over as the switch is thrown.

By the apparatus described, according to the setting of the time switch,thecircuit to the hot plate is closed and opened and coincidently theoutlet valve of theoil cup is opened and closed so that oil will trickledown the tube and drop onto the heated hot plate, which action continuesuntil the setting of the time switch turns off the current and closesthe oil cup valve. When oil drops in this manner upon the hot platesmoky vapor is produced and this smoke is carried up by the' draughtcaused by the heated air, through the pipe to the outlet on thebillboard or sign where it issues with chamber having an outlet adaptedto open throughthe sign, electrically heated means in said chamber, anoil receptacle with its discharge leading into the chamber above saidelectrically heated means, and a time switch, said time switch havingmeans Which coincidently controls anelectric circuit that i 7 includesthe electrically heated means withinthe chamber and the discharge fromthe oil receptacle.

, 2. An apparatus for use in, connection with advertising signswhicheomprises a chamber having an outlet pipe adapted to be extended toan opening through the sign,

electrically heated means in said chamber,

anoili receptacle having a discharge pipe leading on an incline into thechamber above said electrically heated means, and a time switch, saidtime switch having ,mcansf which coincidently controls an electriccircuit that includes the electrically heated means within the chamberand the discharge from the oil receptacle.

3. An apparatus for use in connection with advertising signs whichcomprises a chamber having air intake openings near its lower end and anoutlet pipe extending upward to an opening in the sign, electricallyheated means in the lower part of said chamher, an oil receptacle havinga discharge pi as leading on an incline into the chamber above saidelectrically heated means, anda time switch, said time switch havingmeans which colncidently controls an electric circuit that includes theelectrically heated means within the chamber and the discharge from theoil receptacle.

4. An apparatus for use in connection -with advertising signs whichcomprises a chamber having an outlet adapted to open through the sign,electrically heated means in said chamber, an oil receptacle with itsdischarge leading into the chamber above said electrically heated means,and a time switch, said time switch having a' switch which controlsanelectric circuit that includes the electrically heated means withinthe chamber and having a cam which controls the discharge from the oilreceptacle, said controlling means operating coincidentally.

5. The combination with an advertising sign of a chamber attached to thesign and having an outlet adapted to open through the sign, electricallyheated means in said chamber, an oil receptacle adjacent to said.cl'ian'iber and having its discharge leading on an incline into thechamber above said electrically heated means, and a time switch, saidtime switch having means which coincidently controls an electric circuitthat includes the electrically heated means within the chamber and thedischarge from the oil receptacle GEORGE n.
